Question
Problem 19. 100 µA. If the applied voltage is 2 mV at a frequency of 200 kHz, and the circuit inductance is 50 µH, find (a) the circuit resistance, and (b) the circuit capacitance. The current at resonance in a series L-C-R circuit is (a) 1=100 µA = 100 x 10-6 A; V = 2 mV = 2 × 10-3 V At resonance, impedance Z = resistance R V. 2 x 106 Hence R = 20 S 100 x 10³ (b) At resonance XL =Xc 1 i.e. 2n fL = %3D 2nf C
